Installing Serviceguard Extension for RAC
Installing Serviceguard Extension for RAC includes updating the software and rebuilding the
kernel to support high availability cluster operation for Oracle Real Application Clusters.
Prior to installing Serviceguard Extension for RAC, the following must be installed:
• Correct version of HP-UX
• Correct version of Serviceguard
To install Serviceguard Extension for RAC, use the following steps for each node:
NOTE: For the up to date version compatibility for Serviceguard and HP-UX, see the SGeRAC
release notes for your version.
1. Mount the distribution media in the tape drive, CD, or DVD reader.
2. Run Software Distributor, using the swinstall command.
3. Specify the correct input device.
4. Choose the following bundle from the displayed list:
Serviceguard Extension for RAC
5. After choosing the bundle, select OK to install the software.
Veritas Cluster Volume Manager (CVM) and Cluster File System (CFS)
You may choose to configure cluster storage with the Veritas Cluster Volume Manager (CVM)
instead of the Volume Manager (VxVM). The Base-VxVM provides some basic cluster features
when Serviceguard is installed, but there is no support for software mirroring, dynamic
multipathing (for active/active storage devices), or numerous other features that require the
additional licenses (on HP-UX releases that support Veritas CFS and CVM; see “About Veritas
CFS and CVM from Symantec” (page 18)).
The VxVM Full Product and CVM are enhanced versions of the VxVM volume manager
specifically designed for cluster use. When installed with the Veritas Volume Manager, the CVM
add-on product provides most of the enhanced VxVM features in a clustered environment. CVM
is truly cluster-aware, obtaining information about cluster membership from Serviceguard
directly.
Cluster information is provided via a special system multi-node package, which runs on all nodes
in the cluster. The cluster must be up and must be running this package before you can configure
VxVM disk groups for use with CVM. Disk groups must be created from the CVM Master node.
The Veritas CVM package for version 3.5 is named VxVM-CVM-pkg; the package for CVM
version 4.1 and later is named SG-CFS-pkg. CVM allows you to activate storage on one node at
a time, or you can perform write activation on one node and read activation on another node at
the same time (for example, allowing backups). CVM provides full mirroring and dynamic
multipathing (DMP) for clusters. CVM supports concurrent storage read/write access between
